Hi Damien,
I've checked and double-checked, and I can't see anything not 32-bit. In fact
my VS2005 only knows about 32-bit.
I just tested copying the source code with appropriate include directories to
another directory and built the executable successfully with mpicc. But I can't
see that there is anything in the mpicc link (with --showme:link) that is not in
VS. The command line in VS has a lot more stuff in it, to be sure.

Gib,
If you have OMPI_IMPORTS set that usually removes those symbol errors. Are
you absolutely sure you have everything set to 32-bit in Visual Studio?

I am building the Sundials examples, with MS Visual Studio 2005 version 8
(i.e. 32-bit) on Windows 7 64-bit. The OpenMPI version is OpenMPI_1.6.2-win32.
All the parallel examples fail with the same linker errors. I have added the
preprocessor definitions OMPI_IMPORTS, OPAL_IMPORTS and ORTE_IMPORTS. The
libraries that are being linked are: libmpi.lib, libmpi_cxx.lib,
libopen-pal.lib, libopen-rte.lib.
Here are the errors:

What am I missing?
